Both nitrites and nitrates are negatively charged ions, which means that the combined protons in these molecules are outnumbered by the electrons This compound is used for the curing of meat because it prevents bacterial growth and, in a reaction with the myoglobin in red meat, gives the product a darker red color. This nitrite, however, poses at least two problems. First, it is toxic at relatively high concentrations—the lethal dose of nitrite for humans is about 22 milligrams per kilogram body weight. For this reason, the maximum allowed nitrite concentration in meat products is 200 parts per million (ppm). Second, under conditions such as cooking, nitrites in meat can react with the degradation products of amino acids to form nitrosamines, which are known carcinogens. For this reason, many nutritionists recommend the avoidance of red meats and other foods that contain sodium nitrite.
Alkyl nitrites are chemical compounds with the general structure R-ONO. Formally, they are alkyl esters of nitrous acid. Methyl nitrite and ethyl nitrite are gases at room temperature and pressure, and the next few (larger) members of the series are volatile liquids. The compounds have a distinctive fruity odor.

A simple procedure for drawing Lewis structures was given in a previous post entitled Lewis Structures and the Octet Rule Nitrites usually are prepared by absorption of nitric oxide and nitrogen dioxide in an alkaline solution. In an older method, sodium nitrate was fused with lead, and the resulting sodium nitrite was dissolved in water and separated from the by-product, lead oxide, by filtration.

. Nitrates and nitrites are used in pickling and curing brines to preserve meats, and in certain machine oils and antirust.. Sodium nitrite is used as a food preservative and in reddening meats. Many nutritionists recommend the avoidance of foods that contain sodium nitrite because it can undergo chemical reactions that produce nitrosamines, which are known carcinogens. Sodium nitrite is also used in dyeing textiles, bleaching fibers, photography, metal coatings, and the manufacture of rubber chemicals. In medicine, it has been used as a vasodilator, bronchodilator, and intestinal relaxant or laxative. Both sodium nitrite and amyl nitrite may be used to treat heart disease and cyanide poisoning. Amyl nitrite, also called pentyl nitrite, is an alkyl nitrite that contains five carbon atoms per molecule. Typically, the term refers to the chemical compound with the formula (CH3)2CHCH2CH2ONO. Like other volatile alkyl nitrites, it has a characteristically penetrating odor and produces marked effects on the human body when its vapor is inhaled. It acts as a vasodilator (expanding blood vessels and thus lowering blood pressure) and finds applications in medicine in the treatment of heart disease such as angina. Amyl nitrite is also used to treat cyanide poisoning by inducing the formation of methemoglobin, which sequesters cyanide as nontoxic cyanomethemoglobin.

Nitrites are oxidized by permanganate ions in acidic medium with the formation of nitrate ions. The determination consists of a back titration . A common nitrite test can be performed by adding 4 M sulfuric acid to the sample until acidic, and then adding 0.1 M iron(II) sulfate to the solution Sodium nitrite (NaNO2) is a white to slight yellowish crystalline powder. It is very soluble in water and is slowly oxidized by oxygen in the air to sodium nitrate (NaNO3). It is used as a color fixative and preservative in meats and fish.

In organic chemistry, nitrites are esters of nitrous acid and alcohols. They have the general formula RONO, where R is an aryl or alkyl group, and ONO is called the nitrosooxy functional group. An example is amyl nitrite, mentioned below.
The nitrite ion, which has the chemical formula NO−2. Nitrite (mostly sodium nitrite) is widely used throughout chemical and pharmaceutical industries. Nitrite anion is a pervasive intermediate in the nitrogen cycle in nature In inorganic chemistry, a nitrite is a salt of nitrous acid. The salt contains a nitrite ion consisting of one nitrogen and two oxygen atoms. In organic chemistry, a nitrite is an ester of nitrous acid and an alcohol The total number of valence electrons in nitrite ion ( ) is 18 (5 electrons from N, 6 electrons from each O, and one electrons account for negative charge)
. Other nitrites are available through reduction of the corresponding nitrates. Nitrites should be distinguished from compounds and ions that are similar in name or composition, such as the following:

A positive nitrite test indicates that the cause of the UTI is a gram negative organism, most commonly Escherichia coli. The reason for nitrites' existence in the presence of a UTI is due to a bacterial conversion of endogenous nitrates to nitrites. This may be a sign of infection. However, other parameters, such as leukocyte esterase, urine white blood cell count, and symptoms such as dysuria, urinary urgency, fevers, and chills must be correlated to diagnose an infection Nitriitti on ioni NO2- tai typpihapokkeen (HNO2) suola.
